Some cities make a point to connect their bus systems to the neighboring towns. HOWEVER, before even attempting this CALL BOTH SYSTEMS, and confirm the "official" information on the website. "Yeah, Yellow bus arrives at 2:15, and you'll need a transfer to Smalltown Shuttle, which is an extra charge, but that's all." is very likely from one side. Then you call Smalltown Shuttle and discover that they have changed parameters, cut service, (meaning that you can't get back to the transfer point for pickup again that DAY) or otherwise added obstacles that aren't on the website... yet. It's as much a matter of keeping bus-reliant people out of the more affluent small town as it is miscommunication between the two systems.

That's even before bringing in problems with noncompliant bus stops (not accessible to someone pushing a stroller, let alone a rollator or wheelchair).
